• If unusual noise can be heard during operation, consult the dealer.

• Symbols which appear frequently in the text have the following meaning:

Observe instructions
with great care

Strictly prohibited Provide proper earthing

WARNING

• I nstallatio n must be carried o ut by the qualified installer.

If you install the sys tem by yourself, it may cause ser ious trouble su ch as
water le aks, ele ctric sho cks, fire and per sonal in jury, as a result of a system
malfunct ion.

• I nstall the system i n full acc ordance w ith the in struction manual.

Incorrec t installat ion may cau se bursts, personal in jury, wate r leaks, el ectric
shocks an d fire.

• B e sure to use only for househ old and r esidence.

If t his applian ce is inst alled in inferio r env ironment such as mach ine s hop
and etc. , it can c ause malf unction.

•

Use the orig inal accesso ries and the sp ecified com ponents for in stallation.

If parts o ther than t hose presc ribed by us are used, I t may cause water leak s,
electric shocks, f ire and pe rsonal injury.

• I nstall the unit in a location with goo d support.

Unsuitab le installat ion locatio ns can cause th e unit to fall and cause mate rial
damage a nd persona l injury.

• E nsure th e unit is stable w hen installed, so t hat it can withstand earth­quakes a nd strong winds.

Unsuitab le installat ion locatio ns can cause th e unit to fall and cause mate rial
damage a nd persona l injury.

• V entilate the worki ng area well in the even t of ref rigerant leakage d ur­ing insta llation.

If the re frigerant comes into contact with nak ed flames, poisonous gas is
produced .

• W hen install ing in smal l rooms, ta ke preventi on measure s not to exc eed
the dens ity limit of refrige rant in the even t of leaka ge.

Consult the expe rt ab out p revention me asures. If the density o f ref rigerant
exceeds the limit in the event of leakage , lac k of oxygen can occu r, whi ch
can caus e serious accidents .

•

After comp leted insta llation, ch eck that no ref rigerant le aks from the s ystem.

If refrigerant leaks into the room a nd comes into co ntact with a n o ven or
other ho t surface, poisonou s gas is p roduced.

• U se the pre scribed p ipes, flar e nuts an d tools fo r R410A.

Using ex isting parts ( for R22 or R407C) can ca use the unit fail ure and seri­ous acci dents due to burst o f the ref rigerant c ircuit.

• T ighten the flare nu t by torqu e wrench w ith specified me thod.

If the flare nut w ere tightened with excess torque, this may cause bu rst and
refriger ant leakag e after a long peri od.

• D o not open th e operat ion val ves for liquid line and gas lin e until com­pleted r efrigerant piping w ork, air t ightness t est and evacuati on.

If the c ompressor is operated in s tate of o pening operation valves before
complete d connec tion of refrigerant pi ping work, ai r can be sucke d into re­frigeran t circuit, whi ch can cause bust or personal inj ury due to anomal ously
high pre ssure in t he refrig erant.

• D o not put th e drainage pipe di rectly int o drainage channels w here poi­sonous g ases such as sulphid e gas can occur.

Poisonou s gases will flo w into the room through drai nage pipe and s eriously
affect t he user’s health an d safety.

• E nsure t hat no air enters in the refriger ant cir cuit w hen the unit is in­stalled a nd removed.

If a ir en ters in the refr igerant circuit, the pr essure in the refrigerant circuit
becomes too high, which can cause bur st and pe rsonal inj ury.

• D o not proc essing, splice th e po wer c ord, or sh are a socket with other
power plu gs.

This may cause fire or electric shock due to defect ing contact, de fecting in­sulation and over- current e tc.

• T he el ectrical installation must be carried out by the qualifi ed el ectri­cian in accor dance with “th e n orm for electrical work” and “na tional
wiring regulation”, and the s ystem must be conne cted t o the dedicated
circuit.

Power s upply with in sufficien t capaci ty and incorrect fun ction do ne by im­proper w ork can ca use elect ric shocks and fire .

• B e sure to shut off the power before st arting ele ctrical work.

Failure t o shut off the power can cause electric s hocks, uni t failure or incor­rect fun ction of e quipment.

• B e s ure to use the cab les confo rmed to sa fety stan dard and cab le
ampacity for power distribut ion work.

Unconfor mable cables can cause electr ic leak, anomal ous heat production or
fire.

• T his app liance m ust be conne cted to main power suppl y by means of a
circuit br eaker or switc h (fuse:16A ) with a contac t separation of at least
3mm.

• W hen p lugg ing t his ap pli anc e, a p lug conf ormi ng to t he no rm
IEC60884 -1 must be used.

• U se the pre scribed cables for electrical connection, tighten the cables
securely i n terminal block a nd relieve the cabl es correctly to pre vent
overload ing the te rminal bl ocks.

Loose conn ections or ca ble mountin gs can cause a nomalous hea t production
or fire.

• A rrange the w iring in the co ntrol box so t hat it canno t be pushed up
further into the b ox. Instal l the service pa nel correc tly.

1) Operating conditions:

When the outdoor unit is operating with the compressor command speed of other than 0 rps, and when

the outdoor air temperature sensor (TH2) becomes 41ºC or over for 30 seconds continuously.

2) Detail of operation

a) Outdoor fan is stepped up by 3 speed step. (Upper limit speed is 7th speed.)

b) The lower limit of compressor command speed is set to 30 rps and even if the calculated result becomes lower than that

after fuzzy calculation, the speed is kept to 30 rps. However, when the thermo becomes OFF, the speed is reduced to 0 rps.

3)

Reset conditions:

When either of the following condition is satised.

a) When the outdoor air temperature becomes 40ºC or less.

b) When the compressor command speed is 0rps.

(c) Compressor overheat protection

1) Purpose:

It is designed to prevent deterioration of oil, burnout of motor coil and other trouble resulting from the com

-

pressor overheat.

2) Detail of operation
a)

Speeds are controlled with temperature detected by the sensor mounted on the discharge pipe.

(Example) Fuzzy

Notes (1) When the discharge pipe temperature is in the range of 100 to 110ºC, the speed is reduced by 4 rps.

(2) When the discharge pipe temperature is raised and continues operation for 20 seconds without changing, then the speed is reduced again by 4 rps.

(3) If the discharge pipe temperature is still 90ºC or greater but less than 100ºC even when the compressor command speed is maintained for 3 minutes

when the temperature is 90ºC or greater but less than 100ºC, the speed is raised by 2 rps and kept at that speed for 3 minutes. This process is

repeated until the compressor command speed is reached.

(d) Current safe

1) Purpose:

Current is controlled not to exceed the upper limit of the setting operation current.

2) Detail of operation:

Input current to the converter is monitored with the current sensor xed on the printed circuit board

of the outdoor unit and, if the operation current value reaches the limiting current value, the compressor

command speed is reduced.

If the mechanism is actuated when the speed of compressor command is less than 30 rps, the

compressor is stopped immediately. Operation starts again after a delay time of 3 minutes.

(e) Current cut

1) Purpose:

Inverter is protected from overcurrent.

2) Detail of operation:

Output current from the converter is monitored with a shunt resistor and, if the current exceeds the

setting value, the compressor is stopped immediately. Operation starts again after a delay time of

3 minutes.

(f) Outdoor unit failure

This is a function for determining when there is trouble with the outdoor unit during air conditioning.

The compressor is stopped if any one of the following in item 1), 2) is satised. Once the unit is stopped by this function, it is not

restarted.

1) When the input current is measured at 1 A or less for 3 continuous minutes or more.

2) If the compressor command sends a 0 rps signal to the indoor unit 3 times or more within 20 minutes of the power being

turned on.

(g) Inching prevention

When the compressor goes into the thermo operation within 10 minutes since operation start or becomes various dehumidifying

operations, the operation is continued with the lower limit speed forcibly.

(h) Indoor fan motor protection

When the air conditioner is operating and the indoor fan motor is turned ON, if the indoor fan motor has operated at 300 rpm or

under for more than 30 seconds, the unit enters rst in the stop mode and then stops the entire system.

(i) Serial signal transmission error protection

1) Purpose:

Prevents malfunction resulting from error on the indoor ↔ outdoor signals.

2) Detail of operation

a)

When the outdoor unit controller cannot receive signals from the indoor unit

If the compressor is operating and a serial signal cannot be received from the indoor control with outdoor control hav-

ing serial signals continuously for 1 minute and 55 seconds, the compressor is stopped.

After the compressor has been stopped, it will be restarted after the compressor start delay if a serial signal can be re-

ceived again from the indoor control.

b) When the indoor unit controller cannot receive signals from the outdoor unit

i) If the outdoor unit inverter signals cannot be received for 10 seconds continuously during the transfer error check

at the rst time after turning on the power supply, the compressor is stopped immediately.

ii) If the outdoor unit inverter signals cannot be received for 1 minute and 50 seconds continuously, it tries to restart

two time but stops the operation at third failure of restart.

(j) Rotor lock

If the motor for the compressor does not turn after it has been started, it is determined that a compressor lock has occurred and

the compressor is stopped.

(k) Outdoor fan motor protection

If the outdoor fan motor has operated at 75rpm or under for more than 30 seconds, the compressor and fan motor are stopped.

8. MAINTENANCE DATA

(1) Cautions

(a) If you are disassembling and checking an air conditioner, be sure to turn off the power before beginning. When working on

indoor units, let the unit sit for about 1 minute after turning off the power before you begin work. When working on an outdoor

unit, there may be an electrical charge applied to the main circuit (electrolytic condenser), so begin work only after discharg-

ing this electrical charge (to DC 10 V or lower).

(b) When taking out printed circuit boards, be sure to do so without exerting force on the circuit boards or package components.

(c) When disconnecting and connecting connectors, take hold of the connector housing and do not pull on the lead wires.

these service data.

(a) Explanation of terms

Explanation

Term

Service mode

Service data

The service mode is the mode where service data are displayed by flashing of the display lights
when the operations in item (b) below are performed with the indoor controller.

These are the contents of error displays and protective stops which occurred in the past in the air
conditioner system. Error display contents and protective stop data from past anomalous
operations of the air conditioner system are saved in the indoor unit controller’s non-volatile
memory (memory which is not erased when the power goes off). There are two types of data,
self-diagnosis data and stop data, described below.

Self-diagnosis data

Stop data

These are the data which display the reason why a stop occurred when an error display (self­diagnosis display) occurred in an indoor unit. Data are recorded for up to 5 previous occurrences.
Data which are older than the 5th previous occurrence are erased.
In addition, data on the temperature of each sensor (room temperature, indoor heat exchanger,
outdoor heat exchanger, outdoor air temperature, discharge pipe), remote controller information
(operation switching, fan speed switching) are recorded when trouble occurs, so more detailed
information can be checked.

These are the data which display the reason by a stop occurred when the air conditioning system
performed protective stops, etc. in the past. Even if stop data alone are generated, the system
restarts automatically. (After executing the stop mode while the display is normal, the system
restarts automatically.) Data for up to 10 previous occasions are stored. Data older than the 10th
previous occasion are erased.
( Important) In cases where transient stop data only are generated, the air conditioner system

may still be normal. However, if the same protective stop occurs frequently (3 or
more times), it could lead to customer complaints.

Change the remote controller settings based on
the instructions in the table

(*4)

. (See page 34.)

*1: If the buzzer does not sound no matter how

many times you repeat the operation, the
unit ON/OFF button may be faulty.

*2: Set the remote control’s settings on “Cooling

operation,” “Fan speed: MED” and “Set tem­perature: 21ºC.”

Turn off the air conditioner’s power to terminate the
service mode. If you are going to turn the power on
again, wait 1 minute or longer after turning it off.

Turn the air conditioner’s power on again while
pressing the unit ON/OFF button.

Turn off the air conditioner’s power once, then
wait 1 minute or longer.

When in the service mode, when the remote controller settings (operation switching, fan speed switching, temperature

setting) are set as shown in the following table and sent to the air conditioner unit, the unit switches to display of service data.

Self-diagnosis data

What are Self- .......These are control data (reasons for stops, temperature at each sensor, remote controller information)

diagnosis Data? from the time when there were error displays (abnormal stops) in the indoor unit in the past.

Data from up to 5 previous occasions are stored in memory. Data older than the 5th previous occasion are erased.

The temperature setting indicates how many occasions previous to the present setting the error display

data are and the operation switching and fan speed switching data show the type of data.

(a)Inspection of electronic expansion valve

Electronic expansion valve operates for approx. 10 seconds after the power on, in order to determine its aperture. Check the

operating sound and voltage during the period of time. (Voltage cannot be checked during operation in which only the aperture

change occurs.)

1) If it is heard the sound of operating electronic expansion valve, it is almost normal.

2) If the operating sound is not heard, check the output voltage.
